# Dial-Back

The dial-back feature gives users a second option when answering voice mail messages. When enabled, dial-back allows users to dial the caller who left the voice mail, with the option to either keep or delete the original message.

To enable Dial-back, customize an FCOS to include the following feature bits and assign to the mailbox:

- 263 - Store Caller Line Id as a phone or mailbox number

- 264 - Play outside caller user interface (with FCOS bit 280)

- 270 - Enable Dial-Back feature

- 280 - Enable CLI outside caller interface (with FCOS bit 264)

Program an outgoing call prefix for the MiVoice Business ICP:

- Access the MiVoice Business System Administration Tool.

- In the System Options Form, set Outgoing External Call Prefix for Applications to the digit that users dial to access an outside line (this is often "9").

Prompts received by voice mail users are dependent upon FCOS programming. The voice mail "Answer" operation is independent of dial-back operation so you can enable feature bits for one, both, or neither. The table below describes NuPoint voice prompts for each scenario:

If your system is configured for... | and the voice mail you receive is from... | when you press the Answer key, the NP-UM TUI responds with...
--- | --- | ---
Answer AND Dial-back | another mailbox on the network | the following options: - press 8 for Voice mail answer - press 3 for Dial-back and delete message - press 5 for Dial-back and keep message
an external (local or long distance) caller * | the following options: - press 3 for Dial-back and delete message - press 5 for Dial-back and keep message
Answer only | another mailbox on the network | with immediate “answer with a voice mail” operation
an external (local or long distance) caller | [No Answer key option is available in the TUI menu.]
Dial-back only | another mailbox on the network | with dial-back options: - press 3 for Dial-back and delete - press 5 for Dial-back and keep
an external (local or long distance) caller *
Neither Answer nor Dial-back | Any call | [No Answer key option is available in the TUI menu.]

*Dial-back will attempt to dial the numbers in the Calling Line Identification. Correct dial-back for long distance and International calls is dependent upon programming in the MiVoice Business ICP. For more information, see the Automatic Route Selection topic in the Features Reference section of the MiVoice Business ICP System Administration Tool Help.

## Conditions

- The dial-back feature requires MiVoice Business Release 4.0 (formerly MiVoice Business ICP Release 10.0) or later software on the MiVoice Business ICP

- Dial-back is not supported for SIP integrations like the 5000 CP.

- If a user selects the option to "dial-back and delete message", and then the call is not completed, the original message is restored to the voice mailbox.

- The dial-back feature will not work for messages that have been stored using a version of NP-UM prior to Release 4.0.

## Wait Prompts

When the Wait prompt is enabled, the server issues the prompt “Please enter a mailbox number, or wait” immediately after the server greeting is played. The default value is Y (enabled).

To disable this prompt, you must enter N. In some cases, you must disable the Wait prompt for any number of reasons, among them:

- To record the company greeting (administrator’s mailbox greeting) and the Wait prompt in the same voice. The text of the Wait prompt is recorded as the last sentence of the company greeting.

- When neither a system attendant’s number nor an attendant’s mailbox is defined, and the Wait prompt is enabled, callers who wait are thanked for calling, then disconnected.

- If you disable the Wait prompt and are using the Dial-by-Name function, you must record the “Press [digit] to dial by name��� prompt in your own voice. The server prompt for Dial-by-Name plays if the Wait prompt is enabled.
